Description :
    预置条件：
        1.创建事件触发器函数：
        CREATE OR REPLACE FUNCTION f_eventtrigger_0036()
        RETURNS event_trigger
        LANGUAGE plpgsql
        AS $$ BEGIN
        RAISE NOTICE 'test_event_trigger: % %', tg_event, tg_tag;
        END;
        $$;
    测试步骤：
        1、create EVENT TRIGGER EVENT ON ddl_cmmand_start execute procedure f_eventtrigger_0036();
        2、create table event(a int);
Expect      : 
        1、创建失败
        2、创建成功
